mounted in said base, said arms being mounted on opposite sides of said base, a supporting member pivotally suspended from said arms in such manner that a point on said member moves along a substantially straight line.'

7. A pull rod carrier comprising a pair of spaced upright posts, a pair of horizontal beams, one on either side of said posts, supported on said posts, a pair of spaced apart upstanding arms having horizontal projections at their lower ends which are pivotally mounted in said beams, said arms being mounted from opposite sides of said beams, a horizontal projection on the upper end of each of said arms portions of which liein the same vertical plane as said posts, and a reciprocable supporting member pivotally suspended from said upper horizontal projections in such manner that a point on said member moves along a substantially straight line when said member is oscillated.

8. A pull rod carrier comprising a pair of spaced upright supports, a horizontal beam on either side of said supports bolted together below the tops of said supports with bolts adjacent said supports, a hook of predetermined length, hooked at one end to the top of each of said supports and hooked at the other end to an adjacent. bolt, a supporting member, means pivotally mounting said member on said beams in such manner that a point on said member moves along a substantially straight line when said member is oscillated, said supports being positioned at such points and extending upwardly such a distance as to permit reciprocation of said first mentioned point within the limits of its substantially straight line motion but to prevent reciprocation beyond such limits.

9. A pull rod carrier including a base comprisingtwo spaced side by side parallel beams, a straight line operating linkage pivoted on said beams, said linkage having means for supporting a horizontally reciprocating pull rodand guiding it in a straight line motion, a pair of spaced upright supporting posts straddled by said beams,

and means securing the beams to the posts.

10. A pull rod carrier including a base comprising two spaced side by side parallel beams, a

straight line operating linkage pivoted on said beams, said linkage having means for supporting a horizontally reciprocating pull rod and guiding it in a straight line motionwhile permitting sliding of the pull rod with respect to the supporting means, a pair of spaced upright supporting posts straddled by said beams, means for securing the beams to the posts, said posts extending into the path of motion of a part of the structure connected with the linkage and constituting two limiting stops for limiting the travel of the linkage.
